Hawaii Statewide ITS Architecture Functional Requirements: Roadway Equipment Coordination Description: This equipment package supports direct communications between field equipment. It includes field elements that control and send data to other field elements. This includes coordination between remote sensors and field devices (e.g., Dynamic Message Signs) and coordination between the field devices themselves (e.g., direct coordination between traffic controllers that are controlling adjacent intersections.). Functional Requirements: The field element shall include sensors that provide data and status information to other field element devices, without center control. The field element shall include sensors that receive configuration data from other field element devices, without center control. The field element shall include devices that provide data and status information to other field element devices without center control. The field element shall include devices that receive configuration data from other field element devices, without center control. Included In: HDOT-HWY Connected Vehicle RSE HDOT-HWY Field Devices

The Hawaiian language uses two diacritical markings. The 'okina is a glottal stop; and the kahako is a macron. The State of Hawaii strongly encourages the use of Hawaiian diacritical markings. The National ITS Architecture tool, Turbo Architecture, does not allow for the Hawaiian diacritical markings to be input and as such, customized service package diagrams, operational concepts and other outputs from Turbo are unable to reflect the diacritical markings. To ensure consistency in this ITS Architecture website, no Hawaiian diacritical markings will be used.
